- Page 16 4. NORMAL REFRIGERATOR FUNCTIONS A domestic refrigerator is comprised of an electric control system and a refrigerating system. Since both systems work together, it is difficult to tell whether the refrigerating system is in good working condition. If any part of the refrigerating system or electric control does not work properly;...
- Page 17 1. COMMON PROBLEMS OF A REFRIGERATOR AND THEIR SOLUTIONS Refrigerator problems are closely related to the quality of components, level of workmanship, and owner maintenance. The parameters generally used to determine the working conditions of a refrigerator include the temperature inside the refrigerator, the operating rate, electrical power consumption, noise level, and other functional indices.

Whistling sounds indicate the release of high-pressure gas from a crack in the pressure tube inside the compressor. iv. Clucking sounds indicate that the suspended spring inside the compressor has broken v.

ANALYSIS OF PROBLEMS AND TROUBLESHOOTING Poor Refrigerating Effect The “poor refrigerating effect “refers to when the refrigerator operates normally, but does not cool to the temperature indicated by the thermostat. Possible causes are discussed and analyzed below: 1) Refrigerant leaks Analysis of Problem...
- Page 20 3) There Is Air Left In The Refrigerating System Analysis of Problem Residual air in the refrigerating system will reduce its refrigerating efficiency. Major effects are an increase in temperature of the segment from the compressor outlet to the condenser inlet and an increase in gas suction and exhaust pressures. However, the gas exhaust pressure will not exceed its rated value.
- Page 21 6) Refrigerating oil in evaporator tubing Analysis of Problem During the refrigerating cycles, small amounts of refrigerating oil may remain in the evaporator tubing. However, if there is considerable refrigerating oil left in the evaporator after an extended period of operation, the heat conduction effect will be severely affected.
- Page 22 v. The temperature of the gas discharge tube drops vi. There is no sound of gas eruption from the liquid in the evaporator, and vii. No gas gushes out of the process tube when cut after shutdown Remedy Check the whole machine, particularly those locations which are liable to leak.
- Page 23 Remedy Dismantle the system. Remove the dry filter and purge the tubing with nitrogen. Next, install a new filter. Then evacuate it and fill with refrigerant. 4) Clogged Filter Analysis of Problem The complete clogging of the filter rarely occurs. Oftentimes, there is an accumulation of paste-like matter formed from dust on the filter.
- Page 24 Analysis of Problem Loose frosting and poor refrigerating effect may occur if excessive refrigerant has been charged into the system. Excess refrigerant will occupy additional space in the evaporator. This will reduce its heat dissipating area, and the phenomenon of “liquid striking” may occur.
- Page 25 Overload of electric motor Analysis of Problem Probably, too many things have been put into the refrigerator, and hence the thermal load exceeds its refrigerating capacity; or in case the power supply voltage drops considerably, the current flowing through the motor will increase drastically making the thermal protector actuate and the fuse blown, and hence the motor stops running.
- Page 26 Remedy Check the input power circuit to see whether there is voltage in the power supply, note: the circuit that is connected to the knife switch. This can be determined with a voltmeter or a test pencil. If a blown fuse is found, ascertain and remove its cause, then replace it with a new one of the same specifications.
- Page 27 D) Problems Of Motor And Other Electrical Faults i) Motor Windings Are Damaged Or There Is A Short Circuited Between Turns Analysis of Problem When motor windings are damaged or there the occurrence of a short circuit between turns, the fuse will be blown repeatedly, and the blowout particularly occurs at that instance where you close the knife switch.
- Page 28 iii) How do you know that the shaft and piston have been seized When the refrigerator is switched on, the compressor will not start running. A slight hum sound will be heard and several seconds later, the thermal protective relay will actuate and open the contacts. This process will occur repeatedly, but the compressor will not start.
- Page 29 Remedy If it has been found that the refrigerant in the system is insufficient in quantity, recharge it with refrigerant. In case clogging occurs, disassemble the part where it is blocked. If the evaporation temperature is too high, settle this problem with an appropriate quantity of refrigerant.
- Page 30 case, the fuse will blow. Check the 3-prong outlet to see whether the live wire and the null line are inversely connected. One possibility is that the live wire and null line of the outdoor power supply circuit have been inversely connected; this makes the null line become a live wire.
